To all whom it may concern:

Be it known that we, Jenn M. Roster and J OHN HAWLEY TAUBSIG, bothcitizens of the United States, and residents of Philadelphia in thecounty of Philadelphia and State Of Pennsylvania, have jointly inventeda certain new and useful Process of Regulating the Temperature ofCombustion, of which the following is a specification.

The principal objects of the present invention is to provide an improvedprocess for the application of gaseous products of combustion to thecontrol of the temperature of the products of combustion.

The process will be claimed at the end hereof, but will first bedescribed in connection with the accompanying drawings which show two ofthe many forms of apparatus in connection with which the invention maybe practised.

In the drawings, Figure 1,,is a side view, partly in section, of a coalgas retort bench in connection with which the process of our inventioncan be ractised. Fig. 2, is a transverse sectional view of the same, andFig. 3, is a view, partly in longitudinal section, illustrating amodified construction of coal gas retort apparatus in connection withwhich the invention can be practised.

Referring to Fig. 2, a supply of com-.

bustible gas is maintained within the chamber 1, as shown, by generatin.it in that chamber and the path of trave of this gas is from chamber 1through the passage 2 t0 the retort chamber 3. In the passage 2 the gasis ignited by the addition of secondary air and productsof combustionare thereafter added to it so as to control the temperature eifect, allas will be described. The flues 4 of the recuperator receive the prodnets of combustion from the chamber 3 and they range from front to backof the settin alternately and downward and connect wit-i the stack 5.Secondary air entering for example at s traverses the lines 6 of therecuperator and is introduced into the passage 2, causing ignition ofthe gas which is generated in the chamber 1 and permitting of itssubsequent combustion in the retort chamber 3. Someof the products ofcombustion which would ordinarily pass to the stack are introduced as adiluent in the passage 2. This is accomplished by the passage 8 thatleads to the tines 4 and to a specially provided'flu'e 9 that runslengthwise and in the direction of the flues 4: and has communication byopenings 10 with the passage 2, beyond the zone or region of ignition.In the flue 9, an injector 11 is shown which serves to insure thepassage of products of combustion from the flue 4: through the passage 8to the passage or flue 9 and hence by the openings 10 to the passage 2.This injector may be operated by steam or by air, or by any appropriatemeans. As a matter of fact the injector is merel illustrative of someappliance for intro ucing products of combustion. t are fines which bythe ports deliver air into the chamber 1 for use in generating gas fromsuitable fuel arranged in the chamber 1.

In Fig. 3, the fluid combustible is generated in a roducer 12, whichconstitutes a separate piece of apparatus from the retort bench and maybe common to a number of retort benches. In this construction gas fromthe roducer 12 enters the chamber 1, instead oi being generated in thatchamber, otherwise the construction and mode of operation is the same ashas been described in connection .with Figs. 1 and 2; that is to i 7 arearranged in the cham- What We claim is: 1 In testimony whereof we havehereunto The rocefss ofbregulatin tlzhe temperasigned our names. ture eeat 0 com ustion w ic consists inburning "a mixture of undiluted airandun- 'TAUSSIG diluted homogeneous producer gas, and adding to the burningroducts thereof a diluent Witnesses: consisting of incom ustibleproducts of com- H.
